* [PATCH] headers: detach sched.h and mm_types.h

From: Alexey Dobriyan @ 2010-03-11 18:31 UTC (permalink / raw)
  To: torvalds; +Cc: linux-kernel, linux-arch

* remove mm_types.h inclusion and the rest of mm stuff from sched.h to
  make sched.h inclusion cheaper.
* move stuff to linux/mm.h
* move init_mm declaration to mm_types.h to overcome interdependencies
  on sparc64
* remove linux/aio.h inclusion, it wasn't needed in sched.h,
  no need to move it.

Patch not exactly well compiled tested as I'd like, still survived many
configs across 10 arches and even UML.
